The line of best fit and the correlation coefficient are calculated for a set of data. The value of the correlation coefficient is r =-0.95. What is the strength and type of the correlation for this data?

a) strong and positive
b) weak and positive
c) strong and negative
d) weak and negative

you only have two options: strong vs weak, and positive vs negative.

Do a little studying, and the choice should be clear.
Post your results if you need validation.

strong and negitive

To determine the strength and type of the correlation for this data, we can look at the value of the correlation coefficient (r).

The correlation coefficient ranges from -1 to +1. A positive value indicates a positive correlation, meaning that as one variable increases, the other variable also tends to increase. A negative value indicates a negative correlation, where as one variable increases, the other variable tends to decrease.

Furthermore, the absolute value of the correlation coefficient indicates the strength of the correlation. The closer the absolute value is to 1, the stronger the correlation. A value of 1 indicates a perfect correlation, while a value of 0 indicates no correlation.

In this case, the correlation coefficient is r = -0.95. Since the value is close to -1, this indicates a strong negative correlation.

Therefore, the answer is:

c) strong and negative
